Protein detail:
| Protein name | ORF3a protein |
| Uniprot protein ID | P0DTC3 |
| Protein length | 275 amino acids |
| Protein description | ORF3a is a non-structural protein of SARS-CoV-2 localized at the surface. It is the largest accessory factor that contains 275 amino acids, and shows broad functions, such as enhancing viral entry within the host, regulating the pro-inflammatory cytokine and chemokine production, participating in ion channel formation as well as modulating release of virus from the host cell. |

| Evidence | We investigated each SNP to determine if there were any non-synonymous mutations in genes important to the virus lifecycle. Several non-synonymous mutations were found in the following genes: orf1ab, orf3, N, orf8, and orf10 (Table 4A). |
